Avoid Internal Getters/Setters

[GoogleCodeExporter]

I am a fan of Dudo, and recently I am writing a static code analysis tool to 
conduct performance analysis for Android apps. I found Internal Getters/Setters 
in Dudo's code. 

As suggested by Android Developers,"In native languages like C++ it's common 
practice to use getters (i = getCount()) instead of accessing the field 
directly (i = mCount). This is an excellent habit for C++ and is often 
practiced in other object oriented languages like C# and Java, because the 
compiler can usually inline the access, and if you need to restrict or debug 
field access you can add the code at any time.

However, this is a bad idea on Android. Virtual method calls are expensive, 
much more so than instance field lookups. It's reasonable to follow common 
object-oriented programming practices and have getters and setters in the 
public interface, but within a class you should always access fields directly."



We found the violations in these class:
Class name: com.caverock.androidsvg.SVGAndroidRenderer
--Handler name: 
com.caverock.androidsvg.SVGAndroidRenderer.updateStyle(Lcom/caverock/androidsvg/
SVGAndroidRenderer$RendererState;Lcom/caverock/androidsvg/SVG$Style;)V
--Called inner Getter or Setter: 
com.caverock.androidsvg.SVGAndroidRenderer.getCurrentFontSize()F



Class name: net.margaritov.preference.colorpicker.ColorPickerDialog
--Handler name: 
net.margaritov.preference.colorpicker.ColorPickerDialog.updateHexLengthFilter()V
--Called inner Getter or Setter: 
net.margaritov.preference.colorpicker.ColorPickerDialog.getAlphaSliderVisible()Z

--Handler name: 
net.margaritov.preference.colorpicker.ColorPickerDialog.updateHexValue(I)V
--Called inner Getter or Setter: 
net.margaritov.preference.colorpicker.ColorPickerDialog.getAlphaSliderVisible()Z

--Handler name: 
net.margaritov.preference.colorpicker.ColorPickerDialog.setAlphaSliderVisible(Z)
V
--Called inner Getter or Setter: 
net.margaritov.preference.colorpicker.ColorPickerDialog.getColor()I

--Handler name: 
net.margaritov.preference.colorpicker.ColorPickerDialog.setHexValueEnabled(Z)V
--Called inner Getter or Setter: 
net.margaritov.preference.colorpicker.ColorPickerDialog.getColor()I


Class name: com.caverock.androidsvg.SVG
--Handler name: com.caverock.androidsvg.SVG.getViewList()Ljava/util/Set;
--Called inner Getter or Setter: 
com.caverock.androidsvg.SVG.getElementsByTagName(Ljava/lang/Class;)Ljava/util/Li
st;


Although I admit that it is a minor issue, but I sincerely hope that it can 
help you to improve Dudo.
